Collatz Conjecture has been chosen as the GPU project from the 07 - 12 May so it will be concurrent with Rosetta.  See this link http://www.seti-germany.de/blog/category/boinc-pentathlon/

The 3rd project of the BOINC Pentathlon in the discipline Showbag is:
World Community Grid

All credits granted between
05/10/2012, 0.00 (UTC) and
05/15/2012, 0.00 (UTC) will be taken into the BOINC Pentathlon validation. Please note that pending credits cannot be taken into account! The statistics for this project can be found at
http://www.seti-germany.de/boinc_pentathlon/statistiken/challenge.php?challengeid=3.


WCG goes from 10 - 15 May.
So WCG starts as soon as Rosetta finishes. Hmm, this is a strange system, if Pentathlon runs until the 18th and all projects have a 5 day runtime then 3 CPU projects will be overlapping in the last week. Still, Australians are traditionally at home in the water so no trouble for us to be shooting and swimming at the same time while on horseback.;D

So Rosetta is up first starting at 05/05/2012, 0.00 (UTC).
What would that be in East Australia time?

That's about 10am Sydney time Saturday.  If you press the home button at the top of the page there is a countdown in the news section.

Well that was good timing, SIMAP is out of work so I have switched to Rosetta.

I've chosen 1 hour runtime as this has given me the best Rosetta credit in the past. Makes it easier for changeover to WCG too. Have kept cache small as they want results back quickly for CASP 10 workunits.* Had to uninstall theSkyNet for 5 days because hard disk started to thrash due to big memory Rosetta tasks, one task was using 763MB!

I will choose a zero redundancy project for WCG so there will be no pending.

Good luck and good crunching to all Pentathletes.:thumbsup:


*CASP 10, a community wide experiment in structure prediction starts tomorrow on May 1st and runs to August 1st. During this time we will be using BOINC heavily for structure prediction. If your work unit starts with the label rb you're running a CASP 10 target! rb is short for Robetta which is our publicly available server for structure prediction....for CASP we need results back within a day or two, as our approach is iterative: we analyze the results after one day and send out another set of wu based on these results for two days of computing, then collect the results and submit to CASP. so please do set your buffer to a shorter time, and let us know if you are running out of wu. thanks!

An observation on Rosetta. 

Rosetta work units in Windows on my i7 windows 7/Vista 64 bit PC's are always granted less than claimed but on my two Q6600's Linux 64 bit PC's they are always granted more than claimed.


Windows is getting between 19 -20 credits per work unit per hour
Linux is getting between 23 - 27  credits per work unit per hour.

Dropped to 17 th position now.  Not too bad as there is under 100 members participating, but they don't know it's on most probably as few members use the forum.

This is painful.   It might be a pentathlon but it is fast becoming a COMPUTATIONAL ERROR- LON.

My 32 bit Win 7 machine crashes out with every WU.
My Q6600 64 bit Win 7  is starting to settle down but has had its share of crashes.
My I7 3930 64 bit Win 7 was going OK with only a few crashes but now I am trying fun Collatz on my twin GPU, all the WUs for Rosetta are finishing then crashing.

This sort of thing

always the same error no matter which machine.

Trolled through Rosetta's boards looking for a solution and there doesn't appear to be a fix.   Lots of crunchers have given up and gone elsewhere as this has been going on for 3 months now.

The opsys says he thinks it is either BOINC 7.0.XX series and has suggested we go back to 6.10.xx or maybe it is the GPUs.

Now running just Rosetta (16 threads).  Will see what happens today.  It either improves or I am out of here.

The only machine working without any problem is my IMAC.

:furious: :furious: Bashhead

Morning LawryB

Sorry to hear about your machiines crashing, are you still using 7.0.24 by chance on your machines?  Some other projects are reporting issues with 7.0.24 and advising to upgrade to 7.0.26, which may solve the problem, but then again it could be a different problem thats hitting your computers.

I have not much else to help you with, as I am running Rosetta in my Linux VM and its still using BOINC version 6 trunk.  My windows is running BOINC 7.0.26, but its in standby awaiting for the next project to crunch in the Pentathalon (I did run some Collatz on Friday night it they ran well and validated).

This information may or may not help, but I hope it does for someone.

Happy Crunching
Regards

Hi Tazzduke and thanks.   Running 7.0.25 and now swapping up to 7.0.27 on the 64 bit and back to 6.10.whatever on the 32bit machines.
7.0.26 I think addressed the High Priority issue of previous versions.
Rosetta is looking OK as long as it is the only BOINC project I am running but that sort of defeats the purpose of 6 cores (12 threads) and my dual GPUs.
I'll have a bit of a play when the Penthalon has finished and see what happens.
Cheers

I'm starting to have problems with Rosetta also. It hasn't been too bad until today with only every 20th or 30th task erroring after about 20 seconds. But today I have been getting heaps of tasks with huge memory usage. Hard disk is thrashing away quite often. I'll drop down to 5 cores and see if that works. If not I'll turn off hyperthreading, that should fix it. I'll be glad when it's time to switch to WCG, haha now there's a change.;D
